TEKPORE® PROPERTIES
THE MAIN PROPERTIES OF GUARNIFLON® POROUS PTFE

Porous PTFE grades are produced from suspension PTFE powders and specifically they are a mixture of different particle size distributions and hardness degrees to achieve the desired level of porosity.
Taking advantage of the up-to-date technologies and know-how used to process sintered PTFE products, Guarniflon® has developed different grades of porous PTFE with the following main properties:
  • Air flow rates: up to 20 l/hr/cm2 at 20 mbar
  • Water intrusione pressure (WIP): up to 1,2 bar
  • Average pore diameter: up to 50 μm
Filter and safety technology
  • Filter membranes
  • Protective sheaths
  • Dust filters
  • Protective elements for sensors
  • Silencers
  • Pressure balance system
